User Manual

Operate the pump in the rated pressure range and do not exceed the
safety pressure of 9000 psi (600 bar).
Close the valves and tighten the ports when transporting the pump.
Always open the reservoir release valve during operation.
Do not over tighten the connectors or handles to avoid any damage.
Change contaminated media immediately.
Do not let the media level get below the mid line of the reservoir when
the pump is place horizontal.
Keep the outer threads clean.
Additel is not liable for any safety problems or damages caused by
misuse or incorrect operation.

Problem
Cause
Solution
Difficult to increase pressure with
pre-pressurization handle
Hard to fine adjust
it is difficult to turn valves or quick
connectors
A. Vent valve is not closed.
C. Not enough media is in the reservoir.
A. The vent valve is not closed.
C. The is aged or frayed.
E. The connector type is mismatched to the gauge pressure port.
B. The pre-pressurization handle may not adjust easily under high pressure.
sealing ring
B. The O-ring seal is loose or damaged.
D. The pump is not horizontal.
B. The gauges are not connected tight.
D. The thread surface is not smooth
A. Too much force was previously applied.
C. The threads have no lubrication
.
.
Close the vent valve.
Fill with more fluid. Make sure fluid level is high enough after the
gas purging process.
Close the vent valve.
Use the correct adapter.
Adjust pressure by using fine adjustment handle. (Pressure may
need to be decreased with the fine adjustment handle before the
pre-pressure handle can be used).
Replace sealing ring.
Replace the O-ring
Place the pump horizontally to prepare for pressure or vacuum.
Tighten the gauges.
Use Teflon tape on the thread and turn it in tight.
Do not over tighten.
Lubricate the thread.

Remark：.If local atmosphere pressure is 1 bar, the vacuum can reach to 0 85 bar;
If local atmosphere pressure is P, the vacuum can reach to bar.( P 85% )
To reach the best performance oil is recommended
Recommended oil Di ethylhexyl Sebacate Isovoltine
